“A cloud OS makes initially the same as any traditional operating system: it manages applications and hardware,” Microsoft Vice President Michael Park wrote in his blog. This is a very, very far-reaching explanation for an operating system.
I can well imagine that parks colleagues from the Windows group are not necessarily the opinion that the applications running on Windows “manages”. Moreover, any comparison of a cloud OS with a traditional operating system is completely wrong.
First of all, a cloud OS is NO operating system that manages a specific hardware, and this provides applications in a logical format. In all three cloud operating systems, there is a predefined control and management plane for a range of system, network and storage management systems.
At Microsoft, therefore it is called officially a “cloud OS vision” with which the products Windows Server, SQL Server, System Center and Visual Studio in terms of a cloud architecture can be used harmonized.
Microsoft’;s cloud OS is therefore not a software that you can buy off the shelf, but it is a concept that can be improved for building an internal cloud infrastructure of a data center. The question of whether an internal cloud is a cloud at all, let’;;;s leave not taken into account here. This discussion would take us too far.
For further consideration of cloud OS it is enough if we define an internal cloud as a data center whose computing power, storage, and networks are optimized to the maximum load. The individual departments will benefit from this data center cloud service offered as IaaS, PaaS or SaaS.
For the provision of these services are many infrastructure components to manage and monitor. And when this just one or a few consoles is possible to speak of a cloud OS. Thus, already results in a major drawback of all cloud OS concepts: they only work with the management components of the same suppliers.
This is also true for HP, although sitting up with their version of cloud OS to the open source standard of OpenStack. But there are proprietary extensions and other restrictions, such as the use of their own hardware and software. HP also confirmed that it is not a finished software in its cloud OS. “HP cloud OS is not a product but it is an essential and fundamental component of our cloud solutions,” it says on their website.
VMware remains, which was the first of the vCloud provider who has worked towards cloud OS – and after all, vCloud is a genuine product.
But originally lacked essential elements, such as storage and networks. Meanwhile, the expanding and VMware vCloud is clearly calls this platform now a “software-defined data center (SDD). While VMware solution – just like Microsoft – but not subject to hardware limitations, as well as VMware’;;;s SDD requires that its components are made by VMware.
All three vendors have in their cloud OS offers clear then that the control level associated is particularly advantageous in a so-called “hybrid cloud”.
At Microsoft, we think that the shift of workload from its own data center in the Azure cloud, HP has the connection to the HP cloud or a private cloud hosted here at VMware and the combination with the IaaS offering its own or with a partner, of a VMware-based cloud service offering. An easy way to use these hybrid at Microsoft Azure platform since its different services, such as IaaS and PaaS offering.
Conclusion: Whether Microsoft, HP or VMware – in all cloud OS is not an operating system. But a pure PR stunt, it is still not finally makes an additional management platform for controlling the system components much sense and can lead to more flexibility and significant savings in administration.
